ALFRED C. HOBBS, OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TO UNION METALLICCARTRIDGE COMPANY, OF SAME PLACE.

CARTRIDGE RE-ENFORCE PASTING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 237,276, dated February1, 1881.

Application filed May 3, 1880. (No model.)

To all whom it may concern Be it known that I, A. C. HOBBS, a citizen ofthe United States, residing at Bridgeport, Connecticut, have inventednew an d useful Improvements in Re-Enforce Pasting Machines forCartridges, of which the following is a specification.

Paper shells for cartridges are now made with what is well known as are-enforce,

which consists of a short paper tube located within the end of theshell. It has been found very desirable to secure these short tubes inplace by pasting; and my invention relates to a machine adapted toaccomplish this result.

I 57 It has for its objects to automatically feed the open-ended shellssuccessively to an expander and a pasting device and then under are-enforce carrier where the re-enforce is automatically forced intoposition within the head end of the shell; and with these ends in viewmy invention consists in the construction and arrange ment hereinafterdescribed for accomplishing the results named.

In order that those skilled may fully understand my invention, I willproceed to describe,

in detail, the construction of myimproved machine and its mode ofoperation, referring by letters to the accompanying drawings, in which-Figure 1 is aperspective view of a machine embodying my invention. Fig.2 isafront view of the same. Fig. 3 is a side elevation. Fig. 4 is ahorizontal section, taken at the line as w of Fig. 3; Fig. 5, a detailvertical section, 3 5 showing the expanding-plunger and shell, 850.;

Fig. 6, a similar view of the paste-box, plunger, and shell; Fig. 7, asimilar view, showing there-enforce driven home toits place in the endof the shell; and Fig. 8, a similar view,

showing the finished shell in the act of being ejected.

Similar letters indicate like parts in the several views.

A A are the side frames of the machine,

4 5 which are erected upon a bed, B, and rigidly held at the top by abridge or plate, C.

D is a crank-shaft, arranged at the top in suitable hearings in the sideframes, and provided at one end with a power-pulley, E, and

at the opposite end with an eccentric, F.

G is a plunger-carrier, which is connected by a pitman, H, to thecrankshaft D, and adapted to be reciprocated vertically in side guides,I I, secured to the frames A A.

J is the expander-plunger; K, a plunger for forcing the re-e-nforce tubeinto the shell, and L an ejector-plunger, all verticallyand adjustablyarranged in the head G by means of binding-screws, as clearly shown atFig. 1. The head G may be made in one piece, or the for-.wardly-projecting portion N may be made sep arate and secured in placeby bolts a c.

O is a paste-fountain mounted upon the bed and arranged over theshell-carrier, and P is the paste-plunger, arranged to reciprocatevertically in a bracket-bearin g, Q, secured to the side frame, A. Theplunger P is provided with a cap, 0, and spiral spring (I, by means ofwhich it is elevated when released from pressure, an adjustable collar,0, limiting the upward movement.

R is a horizontal rigid arm or tappet secured to the head G, and is soarranged that during the downward movement of said head the tap pet willcome in contact with the cap 0 and force the paste-plunger P down, thespiral spring at returning the plunger when the head ascends. Theplunger P travels through a hole in the bottom of the paste-fountain,the proper quantity of paste being carried therefrom by the annulargroove f, Fig. 6,near the lower end of the plunger.

S is a circular shell-carrier, in which are formed a series of holes, 9,adapted to receive the ordinary paper-shell tubes, the depth of 85 theseholes being such that the paper shells shall project slightly above thesame. This carrier is pivoted to a block, T, secured to the bed B. Aseries of ratchet-teeth, h, are formed on the periphery of the carrierS, so that the same may be rotated by a spring-pawl, U, pivoted to ahorizontally-reoiprocatin g bar, V. Motion is applied to the bar V by awalkingheam, W, which is pivoted at '6 to the side frame, A, andconnected at its upper end to the eccentric F, and at the lower end tothe front end of the bar V. The pawl U is held in operative position bya spiral spring, 70, Fig. 4.

X is a circular plate with a series of pockets, j, for carrying there-enforce tubes. This plate 100 X is pivoted to another plate. Y, whichis mounted upon a post or block, B, secured to the bed B. The re-enforcecarrierX and plate Y extend over the shell-carrier S, as clearly shownat Figs. 1 and 4, the plate Y having a single hole registering with thepockets gj in the two carriers, so that the re-enforee tubes may at theproper time be forced down vertically into the end of the shells, aswill be hereinafter explained. The re-enforce carrier is rotated inunison with the shell-carrier and in a similar manner by a spring-pawl,Z, pivoted to a horizontally-reciprocating bar, 0, which is connected tothe bar V by a head-block, D, (see Fig. 4,) the two bars V and 0 movingin suitable guides or ways D secured on each side of the side frame, A.

Operation The several parts being properly adjusted, the carrier S isloaded with shell-tubes and the carrier X with re-enforce tubes andmotion is imparted to the pulley E. The rotation of the crank-shaft Dcauses the head G to descend. The plunger J is forced into the open endof the shell-tube, brought immediately beneath the same by the rotationof the carrier. The continued rotation of the shaft D then causes thehead to ascend, and in its next downward movement the shell-carrier .isrotated a distance sufficient to carry the previously expanded shellimmediately under the paste-box and plunger, so that as the descent iscontinued. the expanding-plunger J distends another shell, and thepaste-plunger P, carrying a supply of paste, enters the previouslydistended shell and wipes therein a supply of paste. This operation andmovement continues until the first expanded shell, with its supply ofpaste, comes into line with the plunger K, which forces one of there-enforces down and into the open and expanded shell-tube, asillustrated at Fig. 6. A continuation of movementbrin gs the firstshell, with the re-enforce pasted therein, into line with the ejector L,which forces the completed shell down through the carrier-block T, which5 has a hole or channel out therein for that purpose, the movements ofthe several parts being timed to permit of the operation just described.It will be readily understood that new shells and re-enforceztubes maybe fed to their respective carriers either by hand or automatically, itinvolving no invention to apply such feeding mechanism. I do not wish toconfine myself to the exact details of construction and arrangement, asthey may be varied in many particulars without departing from the spiritof my invention, the gist of which rests in the idea of automaticallyfeeding, expanding, and pasting the shell tubes, feeding and depositingin place the re-enforce tubes, and ejecting the completed shells.

What I claim as new, and desire to secure by Letters Patent, is I 1. Thecombination of the rotary shell-carrier S, the vertically-reciprocatingexpandingrier S and head G, provided with projecting 7 5 arm B, thepaste-box O and plunger P, provided with annular paste-carryin g groove,substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.

ALFRED O. HOBBS.
